I am just going to drop my opinion in also... I would trickle the affiliate links in VERY SLOWLY, and monitor changes on your site very thoroughly.
These latest October updates are very odd...
- I have a +2 year old "stupid-thin" 1-hop affiliate site that now ranks #1-4 (That's 1st through 4th) for the money phrase with almost no backlink building that is generating several thousands of daily pageviews. (One of those sites you build to test something and walk away from...oops)
- I also have a very content rich site that was completely duped on Oct 29th and stopped getting ANY traffic from google. (Not dropped from the index, but literally ZERO Google referrals since 10/29)
I would just take great care with affiliate links right now, they seem to have a bullseye on them!
